Description

A feedback cushion device suitable for core stability training in patients with nerve injuries Technical Field

[0001] This invention relates to the field of rehabilitation training equipment technology, specifically a feedback cushion device suitable for core stability training of patients with nerve damage. Background Technology

[0002] Nerve damage can significantly impact posture and balance, especially in patients with central nervous system injuries who often have poor control over their balance and coordination. Therefore, core stability training is necessary to help them better master balance and coordination. Pelvic control is the bridge to lumbar and lower limb stability; improving pelvic coordination and control lays the foundation for stable sitting and standing balance training.

[0003] Chinese patent publication number CN212914343U discloses a posture training cushion, including a base, airbags, pressure sensors, a horn, and a controller. The base includes a base plate and a frame. Two airbags are installed inside the base, arranged side-by-side, with a pressure sensor located in the center of each airbag. The horn is mounted on the frame of the base. The controller is mounted on the base and connects to the pressure sensors and the horn. This design provides objective and sensitive indicators of postural imbalance. The trigger threshold can be adjusted via a control device. In the initial stage, the trigger threshold can be increased, requiring a significant difference in pressure between the two sides to trigger feedback. As training progresses, the trigger threshold can be gradually decreased to achieve a gradual training principle, ensuring consistent and effective seated training over extended periods.

[0004] The posture training cushion provided by the aforementioned patent can sense whether the user's sitting posture is balanced. This type of cushion mainly relies on pressure sensors in conjunction with a speaker to remind the patient of unbalanced posture; however, this reminder method is not perfect, because patients with central nervous system injuries have difficulty adjusting their sitting posture due to poor body coordination. Relying solely on speaker prompts cannot guide patients with central nervous system injuries to accurately adjust their sitting posture, thus limiting the training effect on patients with central nervous system injuries. Summary of the Invention

[0005] The purpose of this invention is to provide a feedback-type seat cushion device suitable for core stability training of patients with nerve damage. It aims to improve the problem that existing training seat cushions mainly rely on pressure sensors and horns to remind patients of unbalanced sitting posture. However, patients with central nervous system damage have poor body coordination, and the horn prompts alone cannot guide them to accurately adjust their sitting posture.

[0006] This invention is implemented as follows:

[0007] A feedback cushion device suitable for core stability training in patients with nerve injuries includes a cushion body, pressure sensors, a gyroscope, and an information processing terminal. Pressure sensors are symmetrically arranged on both sides of the bottom surface of the cushion body, and a gyroscope is located in the center of the bottom surface. Both the pressure sensors and the gyroscope are connected to the information processing terminal, which is connected to a display and a Bluetooth headset. The information processing terminal is equipped with feedback system software for rehabilitation training. The feedback system software includes a visual feedback unit and an auditory feedback unit. The visual feedback unit displays the patient's sitting posture as an image on the display, and the auditory feedback unit issues instructions to the patient to adjust their posture and provides feedback to the patient after the posture adjustment.

[0008] Preferably, the overall structure of the seat cushion body is designed according to ergonomics and conforms to the mechanical distribution characteristics of the patient's buttocks. The surface of the seat cushion body is provided with multiple ventilation holes, and the bottom surface of the seat cushion body is provided with mounting grooves on both sides. The top of the pressure sensor rests against the top of the mounting groove to ensure that the pressure sensor can accurately measure the pressure at the corresponding position.

[0009] Preferably, the seat cushion body is made by 3D printing technology. The patient's seat is scanned with infrared light, and data such as the distance from the buttocks to the front of the knees, the distance between the two buttocks, the distance between the hips, and the height of the waist are used to create an individualized model. Then, the model is printed out using 3D printing technology.

[0010] Preferably, the pressure sensor has an adapter plate on top, the adapter plate is threaded to the mounting groove, the adapter plate has a sensing probe on top, the pressure sensor has a wire at the bottom, and the wire has a connector at the end.

[0011] Preferably, the feedback system software further includes a pressure signal and a balance signal receiving unit, which is connected to both the auditory feedback unit and the visual feedback unit.

[0012] Preferably, the auditory feedback unit includes a pressure and balance distribution judgment module, a voice command module, and a voice encouragement module. The voice command module is used to guide the patient to adjust their sitting posture, and the voice encouragement module is used to provide feedback on the patient's posture adjustment and trunk structure stability. The voice command module and the voice encouragement module are connected to a Bluetooth headset via Bluetooth.

[0013] Preferably, when the visual feedback unit is working, the voice command module prompts the patient on how to adjust their sitting posture. After the patient adjusts their sitting posture and trunk structure stability, the system judges whether the patient's sitting posture is balanced. If the sitting posture is unbalanced, the voice command module continues to guide the patient to adjust their sitting posture. After the sitting posture is balanced, the system prompts the patient to maintain the sitting posture balance and judges the patient's state of maintaining the sitting posture balance. When the patient's sitting posture balance is broken, the voice command module will continue to remind the patient to adjust their sitting posture. The system also records the longest time that the patient has maintained the sitting posture balance within a unit of time and informs the patient.

[0014] Preferably, the visual feedback unit includes a pressure and balance signal to light signal conversion module and an image sensor. The pressure and balance signal to light signal conversion module converts the pressure and balance signals received by the visual feedback unit into light signals, and then transmits the light signals to the image sensor, which transmits the patient's sitting posture image to the display.

[0015] Preferably, the information processing terminal is equipped with training game software for rehabilitation training. The training game software includes racing game software and balance game software. By controlling the different pressures on both sides of the seat body, the car can be shifted to the left or right, and the weights on the balance board can be increased or decreased. By maintaining body balance, the car can be kept in the center or balanced on both sides of the fulcrum, which can play a training role for the patient.

[0016] Preferably, the training game software includes a pressure and balance signal receiving module, a pressure and balance analysis and judgment module, a pressure and balance signal to light signal conversion module, and an image sensor. The pressure and balance signal receiving module transmits the received signal to the pressure and balance analysis and judgment module, which judges the distribution of pressure and balance. Then, the pressure signal is transmitted to the pressure and balance signal to light signal conversion module, which converts the pressure signal into a light signal. Finally, the pressure and balance signal to light signal conversion module transmits the light signal to the image sensor, which displays the game scene on the display.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The bottom of the seat cushion is equipped with a pressure sensor and a gyroscope, both of which are connected to an information processing terminal. The terminal contains feedback system software, which integrates auditory and visual feedback units. The auditory feedback unit uses voice commands to instruct the patient to shift left, right, forward, or backward. The pressure sensor and gyroscope receive the signals after the shift and provide feedback on whether the patient has followed the instructions. Successful shifts are praised with phrases like "Great job!", while unsuccessful shifts are encouraged with phrases like "Keep it up!" This allows the patient to train under commands while receiving real-time auditory feedback, forming a closed-loop model of receiving commands, completing training, and receiving feedback. Simultaneously, the visual feedback unit displays the pressure applied to the seat cushion as an image on a monitor. The auditory and visual feedback units enhance the training effect on the patient, facilitating faster recovery for patients with central nervous system injuries.

[0019] 2. The information processing terminal is equipped with training game software that works with the seat cushion. Patients with central nervous system injuries can use the training game software to adjust their balance and improve their balance through games, thereby achieving better training results.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0032] Example 1

[0033] As shown in Figures 1, 4, 5, and 6, a feedback cushion device suitable for core stability training in patients with nerve injuries includes a cushion body 1, pressure sensors 2, a gyroscope 3, and an information processing terminal. Pressure sensors 2 are symmetrically arranged on both sides of the bottom surface of the cushion body 1, and a gyroscope 3 is located in the center of the bottom surface of the cushion body 1. The pressure sensors 2 and gyroscope 3 facilitate the sensing of the pressure distribution on the patient on the cushion and whether the patient's body is balanced, thus helping to determine if the patient's sitting posture is correct. Both pressure sensors 2 and gyroscope 3 are connected to the information processing terminal. This structure facilitates the feedback of received signals from the pressure sensors 2 and gyroscope 3 to the information processing terminal. The information processing terminal connects to a display and a Bluetooth headset. The display assists the patient in rehabilitation training, and the Bluetooth headset is used to receive instructions. The information processing terminal is equipped with feedback system software for rehabilitation training. The feedback system software includes a visual feedback unit, an auditory feedback unit, and a balance feedback unit. The visual feedback unit displays the patient's sitting posture on the monitor via images. The auditory feedback unit issues instructions to the patient to adjust their sitting posture and provides feedback to the patient on the adjusted posture. The balance feedback unit issues instructions to the patient to adjust their center of gravity and provides feedback to the patient on the adjusted trunk posture.

[0034] As shown in Figure 2, the overall structure of the seat cushion body 1 is ergonomically designed to conform to the biomechanical distribution characteristics of the patient's buttocks, ensuring that the seat cushion body 1 can better assist patients with central nervous system injuries during rehabilitation training. The surface of the seat cushion body 1 has multiple ventilation holes, ensuring that patients do not experience discomfort due to lack of ventilation during prolonged sitting. Furthermore, the bottom surface of the seat cushion body 1 has mounting grooves 11 on both sides for mounting pressure sensors 2; the top of the pressure sensor 2 rests against the top of the mounting groove 11, ensuring that the pressure sensor 2 can accurately measure the pressure at the corresponding location. The seat cushion body 1 is manufactured using 3D printing technology. Infrared scanning of the patient's seat is used to create an individualized model based on data such as the distance from the buttocks to the front of the knees, the distance between the two buttocks, the distance between the hips, and the lumbar height. The model is then printed using 3D printing technology.

[0035] As shown in Figure 3, the pressure sensor 2 has an adapter plate 21 on its top, which is threadedly connected to the mounting groove 11, facilitating the installation and removal of the pressure sensor 2 and its use. A sensing probe 22 is located on the top of the adapter plate 21, used to sense the pressure distribution on the seat cushion. A wire 23 is located at the bottom of the pressure sensor 2, with a connector 24 at its end. The wire 23 and connector 24 facilitate connection between the pressure sensor 2 and the information processing terminal, allowing the pressure signal sensed by the pressure sensor 2 to be easily transmitted to the terminal.

[0036] As shown in Figure 6, the feedback system software also includes pressure signal and balance signal receiving units. The pressure signal and balance signal receiving units are connected to both the auditory feedback unit and the visual feedback unit. This structure allows the pressure signal and balance signal receiving units to transmit the received signals to both the auditory feedback unit and the visual feedback unit simultaneously, enabling the auditory feedback unit and the visual feedback unit to issue corresponding feedback commands based on the pressure distribution.

[0037] As shown in Figure 7, the auditory feedback unit includes a pressure and balance distribution judgment module, a voice command module, and a voice encouragement module. The voice command module is used to guide the patient to adjust their sitting posture, and the voice encouragement module is used to provide feedback on the patient's adjusted sitting posture and trunk structure stability. The voice command module and the voice encouragement module are connected to Bluetooth headphones via Bluetooth. Wearing the Bluetooth headphones ensures that the patient can clearly hear the instructions from the voice command module and the sitting posture adjustment results fed back by the voice encouragement module.

[0038] As shown in Figure 8, when the visual feedback unit is working, the voice command module prompts the patient on how to adjust their sitting posture. After the patient adjusts their posture and trunk structure stability, the module assesses whether the patient's posture is balanced. If the posture is unbalanced, the voice command module continues to guide the patient to adjust their posture. Once the posture is balanced, the module prompts the patient to maintain it and simultaneously assesses the patient's balance. When the patient's posture balance is broken, the voice command module continues to remind the patient to adjust their posture. It also records the longest time the patient maintains balance within a unit of time and informs the patient of this record. This method effectively trains the patient's control over their own balance, facilitating better rehabilitation training.

[0039] As shown in Figure 7, the visual feedback unit includes a pressure and balance signal to light signal conversion module and an image sensor. The pressure and balance signal to light signal conversion module converts the pressure and balance signals received by the visual feedback unit into light signals, which are then transmitted to the image sensor. The image sensor transmits the patient's sitting posture image to the display screen, allowing patients with central nervous system injuries to adjust their sitting posture based on the feedback posture displayed on the screen.

[0040] Working Principle: During use, the pressure sensor 2 and gyroscope 3 on the cushion are connected to the information processing terminal. The feedback system software is then debugged to ensure that the pressure measured by the pressure sensor 2 and gyroscope 3 can be fed back to the software in real time. The patient then puts on Bluetooth headphones and sits on the cushion. The pressure sensor 2 and gyroscope 3 transmit the sensed pressure to the information processing terminal, which then relays it to the feedback system software. The pressure signal and balance signal receiving unit receives the signals and transmits them to the visual feedback unit, auditory feedback unit, and balance feedback unit. The auditory feedback unit issues posture adjustment instructions to the patient based on the pressure distribution and provides feedback on the adjusted posture. The visual feedback unit transmits the pressure distribution signal to the pressure and balance signal to light signal conversion module. This module converts the pressure signal into a light signal, which is then transmitted to the image sensor. The image sensor displays the patient's posture as an image on the monitor, thus assisting the patient in rehabilitation training. Compared with existing technologies, this application has pressure sensors 2 and gyroscopes 3 installed on both sides of the seat cushion body 1. The pressure sensors 2 and gyroscopes 3 are connected to an information processing terminal. The information processing terminal has feedback system software installed inside, and the feedback system software integrates auditory feedback unit and visual feedback unit. The auditory feedback unit gives the patient voice commands to shift left, right, forward, and backward. The pressure sensors 2 and gyroscopes 3 on both sides receive the signals after the shift and provide feedback on whether the patient has shifted according to the command. If successful, praise can be given such as "Great job!" If the shift is not complete, encouragement can be given such as "Keep it up!" This allows the patient to train under command and receive real-time auditory feedback stimulation, forming a closed loop mode of receiving command - completing training - feedback. At the same time, the visual feedback unit can display the pressure on the seat cushion body 1 as an image on the display screen. Through the auditory feedback unit and visual feedback unit, the training effect on the patient can be better achieved, which is conducive to assisting patients with central nervous system damage to recover faster.

The balance feedback unit issues instructions to the patient to adjust their center of gravity and provides feedback to the patient on the adjusted trunk posture.

[0043] As shown in Figure 2, the overall structure of the seat cushion body 1 is ergonomically designed to conform to the biomechanical distribution characteristics of the patient's buttocks, ensuring that the seat cushion body 1 can better assist the patient in rehabilitation training. The surface of the seat cushion body 1 has multiple ventilation holes, ensuring that the patient will not experience discomfort due to lack of breathability even after sitting on the cushion for extended periods. Furthermore, the bottom surface of the seat cushion body 1 has mounting grooves 11 on both sides for mounting pressure sensors 2; the top of the pressure sensor 2 rests against the top of the mounting groove 11, ensuring that the pressure sensor 2 can accurately measure the pressure at the corresponding location. The seat cushion body 1 is manufactured using 3D printing technology. Infrared scanning of the patient's sitting position is used to create an individualized model based on data such as the distance from the buttocks to the front of the knees, the distance between the two buttocks, the distance between the hips, and the lumbar height. The model is then printed using 3D printing technology.

[0044] As shown in Figure 3, the pressure sensor 2 has an adapter plate 21 on its top, which is threadedly connected to the mounting groove 11, facilitating the installation and removal of the pressure sensor 2 and its use. A sensing probe 22 is located on the top of the adapter plate 21, used to sense the pressure distribution on the seat cushion.

The wire 23 and connector 24 facilitate connection between the pressure sensor 2 and the information processing terminal, allowing the pressure signal sensed by the pressure sensor 2 to be easily transmitted to the terminal.

[0045] As shown in Figure 6, the feedback system software also includes pressure signal and balance signal receiving units. The pressure signal and balance signal receiving units are connected to both the auditory feedback unit and the visual feedback unit. This structure allows the pressure signal and balance signal receiving units to transmit the received signals to both the auditory feedback unit and the visual feedback unit simultaneously, enabling the auditory feedback unit and the visual feedback unit to issue corresponding feedback commands based on the pressure distribution.

[0046] As shown in Figure 7, the auditory feedback unit includes a pressure and balance distribution judgment module, a voice command module, and a voice encouragement module.

[0047] As shown in Figure 8, when the visual feedback unit is working, the voice command module prompts the patient on how to adjust their sitting posture. After the patient adjusts their posture and trunk structure stability, the module assesses whether the patient's posture is balanced. If the posture is unbalanced, the voice command module continues to guide the patient to adjust their posture. Once the posture is balanced, the module prompts the patient to maintain it and simultaneously assesses the patient's state of balance. When the patient's posture balance is broken, the voice command module continues to remind the patient to adjust their posture. It also records the longest time the patient has maintained posture balance within a unit of time and informs the patient of this record. This method can effectively train patients with central nervous system injuries to master their own balance, facilitating better rehabilitation training for them.

[0048] As shown in Figure 7, the visual feedback unit includes a pressure and balance signal to light signal conversion module and an image sensor. The pressure and balance signal to light signal conversion module converts the pressure and balance signals received by the visual feedback unit into light signals, which are then transmitted to the image sensor. The image sensor transmits the patient's sitting posture image to the display screen, allowing the patient to adjust their sitting posture based on the feedback posture displayed on the screen.
